Many studies reported that black raspberries contain phytochemicals like ellagic acid, carotenoids and anthocyanins, and significant amounts of vitamins C, E, folic vitamins, minerals and other valuable beneficial compounds known to prevent cancer in animals. Recently, Public Health professor Gary Stoner , Chair of Environmental Health Sciences at Ohio State University, published another study which found rats on a berry-rich diet had fewer malignant tumors than those not on the berry regimen. The reduction in tumor response to a carcinogen in the esophagus and the colon was between 40% and 60%, and the reduction in the oral cavity was about 50% as well.
Stoner's new study demonstrated that the berries influenced the metabolism of carcinogens such that the end result is less genetic damage. And they do this by slowing the growth rate of pre-malignant pre-cancerous cells, and they also stimulate these cells to die rather than to grow. The berries also inhibit formation of blood vessels in cancerous tumors, which retard their growth. Stoner says his research group has begun human trials with a focus on pre-cancerous lesions in the esophagus, mouth and colon sites where the compounds can be absorbed most effectively.
